Nacellidae from Seychelles
Hello,

I have several unidentified shells from Seychells.
For example, these are two different nacellidae(?):

Specimen #1:
<a href="http://ll04.interfree.it/seychelles_1.jpg" target="_blank"><img src="http://ll04.interfree.it/th_seychelles_1.jpg" alt="http://ll04.interfree.it/th_seychelles_1.jpg" style="border:0" /></a>

Specimen #2:
<a href="http://ll04.interfree.it/seychelles_2.jpg" target="_blank"><img src="http://ll04.interfree.it/th_seychelles_2.jpg" alt="http://ll04.interfree.it/th_seychelles_2.jpg" style="border:0" /></a>

Thank you,
ale.v

Hi there. Specimen 1 is a Siphonaria sp, an air breathing mollusc that looks very like a limpet but belongs to a totally different family. The other 2 look like possibly Cellana radiata but a topside view would help.

Dear Dave,

thank you for your answer. I can show the topside view for both the specimens.

Specimen #1:
<a href="http://ll04.interfree.it/seychelles_1b.jpg" target="_blank"><img src="http://ll04.interfree.it/th_seychelles_1b.jpg" alt="http://ll04.interfree.it/th_seychelles_1b.jpg" style="border:0" /></a>

Specimen #2:
<a href="http://ll04.interfree.it/seychelles_2b.jpg" target="_blank"><img src="http://ll04.interfree.it/th_seychelles_2b.jpg" alt="http://ll04.interfree.it/th_seychelles_2b.jpg" style="border:0" /></a>



Looking for the siphonaria, I have found two possible choice:
S. concinna and S. laciniosa, but I don't know if these shells are present in the Seychelles.


Thank you again,

Yes, they are almost certainly <i>Cellana radiata</i>(Born 1778). This species occurs from East Africa to the Pacific. Sorry but I can't help with the Siphonaria, not my forte I'm afraid.

Hi Ale,
I also have found a few Siphonariidae in Seychelles but I identified them all as <i>Siphonaria ferruginea</i> (Reeve 1856).
The biggest of them was 23mm. I can also have that id wrong...

I cannot find any useful information or image about Siphonaria ferruginea, so I can't compare it.
By the way, all my Siphonaria are also smaller than 25mm, as yours.

Hope someone else could help us...
